PURPOSE: Preexisting diabetes is associated with increased morbidity and mortality in cancer. We examined the impact of incident cancer on the long-term outcomes of diabetes. METHODS: Using the United Kingdom Clinical Practice Research Datalink, we identified three cohorts of diabetes patients subsequently diagnosed with breast, colorectal, or prostate cancer, each matched to diabetic noncancer controls. Patients were required to have survived at least 1 year after cancer diagnosis (cases) or a matched index date (controls), and were followed up to 10 years for incident microvascular and macrovascular complications and mortality...

A novel full-inversion-based technique for quantitative ultrasound elastography was investigated in a pilot clinical study on five patients for non-invasive detection and localization of prostate cancer and quantification of its extent. Conventional-frequency ultrasound images and radiofrequency (RF) data (~5 MHz) were collected during mechanical stimulation of the prostate using a transrectal ultrasound probe. Pre and post-compression RF data were used to construct the strain images. The Young's modulus (YM) images were subsequently reconstructed using the derived strain images and the stress distribution estimated iteratively using finite element (FE) analysis...

OBJECTIVES: To examine whether any androgen deprivation therapy use or longer duration is associated with an increased risk of anxiety in patients with prostate cancer. METHODS: We identified 78 552 men aged ≥66 years with stage I-III prostate cancer using the Surveillance, Epidemiology, and End Results-Medicare linked database from 1992 to 2006, excluding patients with psychiatric diagnoses within the year prior or 6 months after prostate cancer diagnosis. Multivariable Cox regression was used to examine the association between pharmacological androgen deprivation therapy and diagnosis of anxiety...

The diagnosis of prostate cancer in elderly men is likely to increase over the next several decades, owing to changing demographics and a rising population of men older than 65 years. Given the heterogeneity and well-documented challenges in screening, diagnosing, and managing indolent versus aggressive prostate cancer, the geriatric patient population is particularly vulnerable to prostate cancer treatment nuances. Clinicians must become familiar with geriatric assessment tools to better answer life-expectancy questions prior to counseling patients on treatment options...

PURPOSE: Prostate specific antigen (PSA) has been widely used as the unique serum biomarker for the diagnosis and/ or pre-diagnosis of prostate cancer (PCa). However, the diagnostic value of PSA is a subject of ongoing debate owing to its lack of specificity, especially when the PSA level is moderately increased (e.g., 4-10 ng/ml). Thus, we suggest the need for identification of a new biomarker to discriminate PCa cases from benign prostatic hyperplasia (BPH) and normal controls (N). METHODS: Urine or tissue samples of PCa patients, BPH patients, and normal controls were systematically collected...

Multiple malignancies are an increasing combination in the recent years in cancer patients, due to prolonged survival rate and to the advances in diagnostic techniques and therapeutic management. We present the case of a patient diagnosed with prostate cancer and metachronous in one year with basal cell carcinoma of the skin and small lung cell carcinoma with lymph nodes and pararectal metastasis. To our best knowledge, this is the only case presented in the medical literature with these three different types of primary malignancy...

Lipid profiles and prostate cancer have a controversial relationship, and the predictive ability of lipids in determining cancer risk estimation is still questionable. This study demonstrates a significance assessment of the plasma lipid profiles of subjects with prostate cancer. Locoregional subjects irradiated with external beam therapy were compared to prostate cancer subjects with bone metastases. The histopathologic diagnosis of 103 subjects (71 locoregional [Group 1] and 32 palliative [Group 2]) were analyzed and compared using their blood samples, total cholesterol (CHL), triglycerides (TG), high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein (LDL) cholesterol...

Prostate Imaging Reporting and Data System version 2 (PI-RADS v2) provides clinical guidelines for multiparametric magnetic resonance imaging (mpMRI) [T2-weighted imaging (T2WI), diffusion-weighted imaging (DWI) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI)] of prostate. However, DCE-MRI seems to show a limited contribution in prostate cancer (PCa) detection and management. In our experience, DCE-MRI, did not show significant change in diagnostic performance in addition to DWI and T2WI [biparametric MRI (bpMRI)] which represent the predominant sequences to detect suspected lesions in peripheral and transitional zone (TZ)...

Advancements in magnetic resonance imaging (MRI) and MRI-ultrasound (US)-fusion targeted biopsy have resulted in a paradigm shift in the diagnosis of prostate cancer by overcoming the limitations of systematic biopsy. Prebiopsy MRI and MRI-US-fusion biopsy results in an increased detection of clinically significant disease, reduction in the detection of indolent disease, and allows for tumor localization during targeted biopsy. With these advantages, we have adopted a prebiopsy MRI and MRI-US-fusion biopsy diagnostic care pathway for all men at risk for prostate cancer and have performed more than 1900 biopsies to date...

Prostate cancer screening offers the opportunity to significantly reduce morbidity and mortality from this disease. Currently, serum prostate-specific antigen (PSA) testing is the most widely used screening modality. However, PSA testing continues to have low positive and negative predictive value leading to unnecessary invasive prostate biopsy while missing patients with aggressive forms of the disease. Magnetic resonance imaging (MRI) has been gaining an increasingly large role in the management of patients with early stage prostate cancer including diagnosis in patients with abnormal PSA levels, monitoring of patients on active surveillance, and staging prior to definitive interventions...

Prostate cancer (PCa) is one of the few neoplasms that are not well served by 18F-Fluorodeoxyglucose (FDG) positron emission tomography (PET). As a result, a number of PET tracers have been developed to target particular biological features of PCa. Such agents can be used for diagnosis, staging, identification of biochemical recurrence (BCR) and evaluation of metastatic disease. Here, we focus on primary disease and local staging. To date, magnetic resonance imaging (MRI) has proven superior to PET in the imaging of primary PCa...

The role of magnetic resonance imaging (MRI) prior to biopsy in the diagnosis of prostate cancer in biopsy-naïve patients has been strengthened by recent developments such as the PIRADS V2 criteria, which cover acquisition, interpretation, and reporting for clinical practice and data collection for research. Important questions on the role of prostate MRI remain: can MRI be used as a triage test before first biopsy series? Can it be used to avoid the use of systematic biopsies (SB) and instead use only targeted biopsies (TB) to MRI-suspicious lesions? Studies to evaluate image guided TB compared to SB have started to accumulate...

Prostate cancer is the second most common cause of cancer related death in the United States and the most commonly diagnosed malignancy in men. In general, prostate cancer is slow growing, though there is a broad spectrum of disease that may be indolent, or aggressive and rapidly progressive. Screening for prostate is controversial and complicated by lack of specificity and over diagnosis of clinically insignificant cancer. Imaging has played a role in diagnosis of prostate cancer, primarily through systemic transrectal ultrasound (TRUS) guided biopsy...

BACKGROUND: Accurate reference intervals (RIs) based on a healthy pediatric population are essential for pediatric test result interpretation. The CALIPER project has recruited a large healthy cohort and completed a series of a priori studies to address gaps in pediatric RIs. As immunoassays from different manufacturers for endocrine and special chemistry markers are not standardized and show marked intermethod differences, direct RI studies are needed for each major analytical platform...

The development of new sensors for the accurate detection of biomarkers in biological fluids is of utmost importance for the early diagnosis of diseases. Next to advanced laboratory techniques, there is a need for relatively simple methods which can significantly broaden the availability of diagnostic capability. Here, we demonstrate the successful application of a sensor platform based on graphene oxide and upconversion nanoparticles (NPs) for the specific detection of mRNA-related oligonucleotide markers in complex biological fluids...
